Abstract

In order to produce a sound post system that is easy to deploy, is position-variable and can be adjusted with little technical outlay even by less technically skilled operators, the disclosure proposes a sound post system that comprises a sound post and an adjustment tool, wherein the sound post comprises a tube that has a contact element hinged to one end of the tube and, at the other end of the tube, a screw mechanism with a support element, said screw mechanism being formed by a mating thread on the tube and a threaded component connected to said support element, wherein a further hinged contact element is disposed on the side of the support element that faces away from the tube and, by actuating the screw mechanism, the distance between said two contact elements can be varied, both the support element and the tube comprising radial holes for the introduction of torque forces, and the adjustment tool comprising a rod for inserting into a radial hole, and a handle that is connected to said rod.

Claims

exact text as granted — not AI-modified
The invention claimed is: 
     
       1. A sound post system, comprising a sound post and an adjustment tool, wherein the sound post comprises a tube that has a contact element hinged to one end of the tube and, at the other end of the tube, a screw mechanism with a support element, said screw mechanism being formed by a mating thread on the tube and a threaded component connected to said support element, wherein a further hinged contact element is disposed on the side of the support element that faces away from the tube and wherein, by actuating the screw mechanism, the distance between said two contact elements can be varied, wherein both the support element and the tube comprise radial holes for the introduction of torque forces, and the adjustment tool comprises a rod for inserting into a radial hole, and a handle that is connected to said rod. 
     
     
       2. The sound post system according to  claim 1 , wherein the tube is made of carbon fiber. 
     
     
       3. The sound post system according to  claim 1 , wherein the mating thread on the tube is an internal thread. 
     
     
       4. The sound post system according to  claim 3 , wherein the internal thread is formed in a threaded sleeve inserted in and fixed to said tube. 
     
     
       5. The sound post system according to  claim 1 , wherein the mating thread on the tube is an external thread. 
     
     
       6. The sound post system according to  claim 1 , wherein the threaded component connected to the support element is a threaded rod. 
     
     
       7. The sound post system according to  claim 1 , wherein the threaded component connected to the support element is a threaded bolt. 
     
     
       8. The sound post system according to  claim 1 , wherein the threaded component connected to the support element is a threaded sleeve. 
     
     
       9. The sound post system according to  claim 1 , wherein the support element is disc-shaped. 
     
     
       10. The sound post system according to  claim 1 , wherein the support element is a nut. 
     
     
       11. The sound post system according to  claim 1 , wherein the screw mechanism comprises a locking unit. 
     
     
       12. The sound post system according to  claim 11 , wherein the locking unit is a lock nut. 
     
     
       13. The sound post system according to  claim 12 , wherein the lock nut has radial holes. 
     
     
       14. The sound post system according to  claim 1 , wherein the radial holes on the tube comprise at least a pair of mutually aligned holes. 
     
     
       15. The sound post system according to  claim 1 , wherein the contact elements are supported by ball bearings with respect to the tube. 
     
     
       16. The sound post system according to  claim 1 , wherein the contact elements are arranged such that they can be exchanged. 
     
     
       17. The sound post system according to  claim 1 , wherein the handle of the adjustment tool comprises a handle and a guide rod at whose end facing away from said handle the rod is arranged.
